Comment (by kencu):

 no, not memory corruption in the app, exactly, I don't think

 This is the error we see caused by the new libgcc_s.1.dylib in gcc7
 conflicting with the old libgcc_s.1.dylib in /usr/lib.

 We saw the same error in several (but not all) gcc7 builds. The exact
 nature of what causes it is not 100% clear to me at least, but it did not
 happen with gcc 7.4.0 and it does happen since then.

 There are two fixes I know of. Build with static-libgcc (I believe that
 will work, haven't actually done it to prove it) or use DYLD_LIBRARY_PATH
 set to /opt/local/lib/libgcc. Or use gcc 7.4.0.

 MacPorts decided to do the DYLD setting fix. There is an option in the
 legacysupport PortGroup to wrap the binaries that error, and set this
 automatically with a wrapper.

 Inspect the legacysupport 1.1 PortGroup, and look in the cmake Portfile
 for a good example.
